Hey everyone, My galaxy s2 has recently been going from half battery to zero instantly and shutting down, or crashing. Upon the most recent crash when i rebooted and charged the phone, it seems like all my app data has be wiped. Whenever i open an app (dolphin browser, facebook, games, twitter, screen lock etc) the phone freezes and the app will force close. this does not happen for a few apps which is weird. is there a way i can fix these issues without uninstalling all my apps or wiping my phone? Thanks!
